I know this is a loaded question and is going to vary by opinion but I am curious to which garden tractor size engine you would prefer and why?

I remember someone mentioned a long time ago that Caterpillar was making a small diesel engine but I haven't really dug up anymore information on it. If they do and it is possibly affordable or comparable in price to others then that would be my favorite. Reason being I have and always will be a Cat guy. It is a shame they don't make the big truck engines anymore but the EPA had their way with that.

I would say my next favorite diesel engine would be a Yanmar. That is what was in my John Deere CUT I had a couple years ago. I know Yanmar makes smaller diesels that would work in garden tractors but I think they might be on the pricier side but I could be wrong there.

As with most things, the best engine may not be the best choice. Parts availability is very important. As tough as most diesels are, they still can need a part now & then.

I think Dan has a real point there. China probably has over 50 companies building diesel engines for the small engine market, and that is a very conservative estimate. If you look at gas engines today, you see Kohler, Tecumseh,Wisconsin
and briggs as the dominant few.
even Onan who arguably built a very good engine did not come out on top. For my part, in the diesel line, I would tend to stay in the Hatz, Deutz, Lister Petter area because of the reasons Dan pointed out. Not only did they hold up good, but repair parts were not that hard to get. Now bear in mind I have not messed with small diesels in the last 15 years so things could have changed a lot. I think the China engines have to get a few years of running behind them before I buy in.

Just my opinion, George

that Caterpillar was making a small diesel engine

My understanding is that Cat purchased Perkins. I have a CAT / Perkins 3 cylinder 28 HP diesel engine in my Cub Cadet 6284 CUT - a sweet little engine. It is designed to run at a higher RPM range than some other diesels and the tach shows the green (operating) range at 3 - 4,000 RPM. It is balky to start in extreme cold weather until you learn to cycle the glow plugs twice and crank through until the engine totally catches, but overall I love it.

Aren't some of those engines nick named Perkapillars or something like that ?It runs in my mind that I remember someone calling those by that name.

I haven't heard that but sounds logical to me. But then so do names like Cataperk, Catkin, D-kin, Bessie, Clarence, Bobbie Jo..... well, you get the picture.:brain_fart:

George,

I like the little Kubota's that you can find in their small GT's. I have owned a332 JD., and loved the Yammar it had.

Thats my 2 cents worth,

Brian

I find the 3 cylinder yanmars quite rattley at low revvs, but they run nicely higher in the rev range.
Kubota make a very fine small diesel indeed, the 3 cylinders in particular.

Mjay,

That rattle is part of the diesel mystique. It takes a little getting used to (the same sound coming from a gas engine would evoke terror in the heart of any GT lover). But, imagine pulling your tractor out of the garage to show your tractor friends with that diesel rattle emanating from under the hood. The expression of envy on the faces of all your 'gasser' friends will be priceless! I think the sound of diesel rattle can be to GT fans like the sound of a Harley is to cycle fans. GO FOR THE RATTLE!:rocker:

Lister Petter seems to make a good variety of little diesels. I really like mine.

MF10.

Tell us more about your Lister. Is it air cooled or one that utilizes the hopper water cooled design? If it is the hopper design am I correct that it is not pressurized or circulated? How many RPM is your engine designed to run at and how many HP is it? How about pictures when you get the chance? I am very interested in learning more about your set up.

It is an AC1, 1 cylinder air cooled, OHV, Bosch direct injected, 3600 RPM. It is military surplus, It'll roll coal over the house like a freight train if its really working hard. This conversion has worked well for me, it was forced into service early and has performed well. These were taken when I was working on the swap. It's a tight fit. The gas tank in the pics is no longer, replaced by a stock steel tank modified with a return fitting.

I would like to get my hands on a 3-4 cylinder for a little fun with a turbo, some EDM'd injectors, and pump mods.

MF10,

Very nice. Looks like your tractor and the engine were made for each other.

Thanks for sharing!
